I have been testing vrchat personally on my own on the quest 2 since I got mine and everything ran really well specially the mirrors where I could get 50/60 frames by myself in a world. Now I'm lucky to even get 30/40 and its a frame drop from 90+fps to 30/40. This was not an issue till the past update and this is the only performance issue I've personally seen that is major cause when more people got added to the world I crashed which is something I never had happened on quest 2 previously before the newest update. I had quest 1 users in the same instance saying it was running at 40/50 frames while I could only get 30-37 solid
